comprising means4 forautomatically stripping the inold from the ingot atthe strip- As is well known to those skilled in the art, it isordinarily the practiceto employ :a non-sectional or solid mold arrangedin an u right position upon the 4car platform. l T 's car isi'irst run-tothe point Where the Inoldwill Vreceive the molten metal as it flowsfromthe ladle, and when the mold is filled 'the car is runalong thetrack to the strippingstation, that i-s, to a point opposite `215 .whatis called the soaking pit-.v At this point, the mold is strippedorlifted olf the ingot bythe usual appliances employed for thatpurpose,4 but as is also well known, this stripping process, with 4theordinaryfacilitiesand with'4 the ordinary non-sectional Iniold, isfrequently-attended with difficulty, inasmuch as the ingot is liable tostick .to the mold and under such circumstancesit often becomesnecessary -to shatter the mold tol effect its se aration from 'the inot.

V It is there ore thepurposeoft e present y invention-to provideanimproved ingot mold so constructed and operated as to eifect anfautomatic stripping' of the mold fromthe 40 ingot at the strippingpoint, thus obvi'ating al1 of vthe d-iiiiculties heretofore existing to.the common stripping methods and -atv the same time providing reliablemeans foralways leaving the ingot free from the'inold,

In the embodiment of the invention disclosed in the drawingsfthe 'moldcar'includes 75'.

in itsl general organization a body 7 carrying the wheel axlesSonfiwliich are mounted .the

-wheels 9 that travelo'ri the track rails 1D.

' The platform of tlegjcar carries thereoifa mold base '11, thatisa-base upon which is Supported the ingot 1110141(3a-signmed` i; its.entiretr by the lptter M` @ll-.This mold base 11 preferably consists ofaffseparate 'platede-A tachably mountedv 0r securedbn top ofthe-j carplatform. The detachable vmounting o f` 85 the mold base maybeeifet'xted-A in a variety of ways, but a simpleexpedient-fthat may beresorted' to is suggested in the drztwinga viz':` the featureofvproviding the sai-dbase at its corners or other suitable point'swithdepending holdingv lugs l1 engaginginkeeper' sockets 11.h in the carplatform, but it will be understood that equivalent `fastenings may Inthis connection, it will be observed that the idea of'using a detachableand replaceable mold base' is to permit the same to bel readily replaced when-burned out witlioiit'in any vwise interfering with the bedof the car or the i mechanism carried thereby.

. The ingot mold M is preferably vof the ulpwardly tapering type, butaccording to'v t e present invention', consists of a pair ofI matchingsections l2, suitably hinged, Aas shown at 13, to the base. The loweredges of these mold sections 12 are preferably conv-' vexed, asindicated at 12, to register in c0rV respond' ly concaved seats 12bprovided in'- .l the mold ase, thus forming an interlocking il() ilar4joints, for a similar purpose, are' provided between the meeting edgesof the. separate mold sections.

thereof are crank shafts 16, the cranks 17 of which operate vthroughopenings 18 formed in the car body. These cranks have pitmen connections19 with .the mold sections 12, the pitmen'. being pivoted to ears 20projecting' from the outer sides of the sec- A driven' shaft 21,journaled longitudinally upon -the under side of the car body, has bevelgear connections 22 22l with the crank shafts, so that theirsimultaneous rotation in opposite directions effected. A driving shaft23, journaled in suitable boxes 24 upon the under side of the car bodytransversely thereof, has a worm 25 that meshes with a worm wheel 26mounted on the Shaft 21. It will thus be clear that if i the drivingshaft 23 is rotated, the shaft 21 will be turned, thereby rotating thecrank shafts 16 and the cranks 17, forming parts thereof. As thesecranks swing away from yeach other, the mold sections will be swungapart, and consequently stripped from the ingot cast in the mold. Uponth'e rotation of the shaft 23 in an opposite' direction, the moldsections will be swung together or into assembled relation.;

Different means may be employed for rotating the driving shaft 23. Inthe form of construction, which is probably preferred, a

' rack 27 is mounted between the track rails at or adjacent to thestripping point, and a gear 28, fixed to the driving shaft 23, is sopositioned that it will engage the rackwhen the car is moved over saidrackpthus the separating mechanism will be operated and the moldautomatically stripped from the ingot. When the mold is opened, theingot can be readily removed from the car, as will be obvious, and uponthe return of the car from the stripping point, the mold willautomatically c ose. The worm gear connection between the driving and-driven shafts is important, as it constitutes a lock for holding thesaid sections against accidental By way of -illustrating the .wide rangeof modification'that may be resorted to in carout the invention, thereis suggested in Fig. 6' another form -of operating mechanism that may beemployed. 'j According to this suggested construction, a suitable motor29 may be arrangedalongside of the track providing means for driving alongi- -tudinally shiftable shaft 3() carrying a gearchanical means (notshown) to provide for shifting the gear Wheel 31 into and out of meshwith the gear wheel 28. Hence, when the cai' is moved to the strippingstation; the sha-ft 3() is shifted into engagement with the gear wheel2S, as shown in Fig. 6, whereupon it will be obvious-that the mold canbe opened and closed as described.

Freni the foregoing, it is thought that the construction, operation,and. many advan tages of the herein described invention will be apparentto those skilled in the art, without further description, and it will beunderstood that various changes in the size, shape,

proportion, and minor details of construc-v tion may be resorted towvithout departing from the spirit or sacriiicing any of the ad vantagesof the invention.
